CONNECTER.

Application filed May 8, 1924. Serial No. 711,794.

This invention relates to connecters for electrical conductors and hasparticular reference to connecters for use in connection with the wiringof radio apparatus.

Heretofore radio apparatus has been connected by bending the conductorsinto loop formation for connection to binding posts and also bysoldering the conductors together where they are to be electricallyconnected This procedure involves considerable skill in order to obtaingood electrical contact. and at the same time a neat appearance of thewiring.

It is the general object of the present invention to provide a connecterwhich shall enable inexperienced persons to obtain a neatappearingcircuit and at the same time good electrical contact either with orwithout the use of solder.

Another object is to provide a connecter which shall greatly expeditethe wiring of apparatus and which is adapted to various types ofconnections and to either round or square wire.

A still further object is to provide a connecter of the aforesaidcharacter which shall be simple in construction and inexpensive tomanufacture.

Further and more limited objects will become apparent as the descriptionproceeds.

In the drawing accompanying this application, Fig; 1 is a plan view of aconnecter constructed in accordance with my invention and showing thesame before it is applied to a conductor; Fig. 2 is a longitudinalsectional view taken on the line 22 of Fig. 1; Fig. 3 is a plan viewshowing several different types of connections: Figs. 4 and 5 aresectional views taken on the lines 4-4 and 55 respectively; Fig. 6 is aplan view of a modified form of connecter; and Fig. 7 is a plan viewthereof showing the same applied to a conductor.

Describing the various parts by reference characters 1 denotes myconnecter which is preferably a stamping from sheet metal of goodconductivity, such as brass or copper. The central portion of 'theconnecter is embossed transversely as indicated at 2 and provided withan aperture 3. Adjacent each side of the central embossed portion 2there is formed a longitudinal embossed portion 4 which is substantiallysemi-circular in cross section. Each flattened end portion 5 ofv thedevice is rounded as indicated at 6 and provided with an aperture 7.

Referring to Fig. 3 wherein some of the uses of the connecter are shown,it will be noted that the transversely embossed portion 2 thereof isbent around a conductor 8, and the flattened end portions 5 of thedevice are superimposed, one upon the other with the apertures 7 inalignment and the embossed portions 4 in alignment. The connecter may beapplied to any portion of the conductor 8 or it may be applied to theends of conductors 8 and 8 and a third conductor 8 inserted throughaperture 3 and between the embossed portions 4 thereby forming a rightangled connection therewith. The apertures 7 are adapted to receive abinding post screw 9 as shown in Fig. 4 and when the nuts 1T) aretightened the connector is drawn into snug engagement with theconductors thereby insuring good electrical contact. If desired theconnecters may be tinned and by holding ahot iron to the connecters,.and the conductors, which are usually tinned, they will be sweatedtogether.

In Figs. 6 and 7, I have shown a modified form of connecter which isdevoid of the longitudinally embossed portions and which is particularlyadapted for electrically connecting a conductor 7 in close relationshipto a binding post. In other respects this connecter is identical withthose previously described. being provided with a transversely disposedembossed portion 2 which is adapted to encircle the conductor, andflattened end portions 5 having apertures 7* which are adapted toreceive a binding post screw.

The connecters are made of relatively thin sheet metal and hence readilyadapt themselves to either round or square conductors. Due to the factthat they make good electrical contact without soldering, they may beused for temporary wiring when experimenting with different circuits.They also permit the operator to test a circuit thoroughly when wiredand if found defective the trouble may be easily remedied, after whichthe connections may be made permanent by'soldering if desired.

Having thus described my invention, What I claim is An electricalconnecter of the class described comprising a sheet metal stampingfolded upon itself, the central portion of said stamping beingtransversely embossed and posite ends of said stamping each having anhaving an aperture therein, said stamping aperture therethrough disposedin al1gnbeing provided on each side thereof with a ment with each otherand adapted to relongitudinally extending embossed portion oeive a bolttherethrough for retaining said 5 at right angles to and intersectingsaid connecter in electrical contact with said contransversely embossedportion, said longiductors. tudinally embossed portions being oppositelyIn testimony whereof, I hereunto afiix my disposed and in alignment withsaid apersignature. ture whereby said connecter is adapted to 10 engagea plurality of conductors, the op- EARL H. WISEMAN.
